What’s it about? Control a group of characters in The Cave, a point-and-click adventure-style game in which players work through a side-scrolling world and a number of puzzles.

What’s cool? From the mind of Ron Gilbert, one of the creators behind the classic adventure title Secret of Monkey Island, comes The Cave, a hybrid point-and-click adventure/platforming game. You control three different characters, which you pick from a group of several, to take into the mythical cave in search of an incredible treasure. But along the way, you'll work through puzzles and hear the strange, twisted backstories of the characters, all of which are dark and mysterious. Switching between the multiple characters is also key to solving different puzzles as you go, and you'll get to experience a lot of off-the-wall, humorous stories surrounding the game's seven characters.

Who’s it for? If you like adventure titles and games with a wry sense of humor, The Cave is for you.

What’s it about? Mow down zombies and save survivors in a besieged city in Gunner Z, which puts you in an armored assault truck for the task.

What’s cool? Sure, by now you've probably killed a whole lot of zombies as an iOS gamer, but Gunner Z stands out from the usual fare in a few key ways. For one, it's a shooter with a vehicle component – you're using an armored assault truck to fight the army of undead scattered around the game's destroyed city. For another, Gunner Z makes use of a fairly unique night vision mechanic to set itself apart graphically, and you'll fight more than just zombies as you work through the game's campaign. Successful missions let you customize your vehicle to help you fight through more than 30 missions, and you can also amp up some competition with “friend challenges” or share replays of your action online.
